This study is comparing two types of daily disposable multifocal contact lenses, kalfilcon A and stenfilcon A, for people with presbyopia (age-related farsightedness). Researchers want to see how well these lenses perform. You might be able to join if you are at least 18 years old and already wear soft contact lenses, including multifocal lenses or lenses for monovision. The main goal is to measure your vision with each lens type. The current status of this study is unclear, and it plans to enroll 35 participants.

Study design

This is a double-masked, randomized, crossover study involving 35 participants. You would wear two different types of contact lenses for a week each.

What's involved

You would wear each type of contact lens for 5-7 days. Your vision will be measured at the end of the study, approximately 4 hours after the last lens wear.

Compensation

Not stated in the trial record.

Follow-up

Your visual acuity will be measured at the end of the study, approximately 4 hours after the last lens wear.
